WEBVTT 0 00:00.840 --> 00:06.570 I everyone looking back at this adorable and destructo relatable core and explore the duration class 1 00:06.930 --> 00:14.100 that's darksome They first and then they go into the core duration is it time based representation in 2 00:14.190 --> 00:17.870 our minutes seconds and now seconds. 3 00:19.420 --> 00:24.740 Duration Gause is compatible with local time and local date time. 4 00:24.810 --> 00:30.690 This is used to the present duration of time not just a specific time. 5 00:30.880 --> 00:32.120 What do we mean by that. 6 00:33.410 --> 00:37.050 That say you want to define a duration of three hours. 7 00:37.130 --> 00:42.890 Then its possible by using the fact that there is part of that duration glass which is off. 8 00:42.930 --> 00:46.890 RS this represent a duration of three Rs. 9 00:47.540 --> 00:51.230 That's a 1 percent a duration of three minutes. 10 00:51.270 --> 00:54.300 That is a handy off minutes method that you can use. 11 00:54.400 --> 01:01.310 That is part of the duration clause in order replacement or duration of 30 or 40 minutes. 12 01:01.500 --> 01:08.070 The most general use case of duration is dark to calculate the difference between the two objects or 13 01:08.100 --> 01:12.180 the time objects can be local time and local Date Time. 14 01:12.210 --> 01:18.120 Let's take a look at this example this example a particular part of the Loper time represents seven 15 01:18.120 --> 01:23.100 Archstone dominance and the local time warner presents 8 hours and 30 minutes. 16 01:23.100 --> 01:30.000 If you posit those two times that between moderate is going to give you the difference between those 17 01:30.330 --> 01:35.720 two instances that go higher and explore this using some examples. 18 01:36.280 --> 01:41.950 When I go back to the Including And in the time dates back Ajam to read of class 19 01:45.410 --> 01:56.890 on batting Nimes you Rhaetian example and then want to make discloser you go to will be arding public 20 01:56.890 --> 01:59.090 static wide beam of that. 21 01:59.110 --> 02:05.620 Now let's read that to final instance before that I'm going to pull this in doesn't Dushan more so that 22 02:05.620 --> 02:06.260 before. 23 02:06.430 --> 02:07.030 We'll King or 24 02:11.110 --> 02:12.380 local time. 25 02:12.590 --> 02:14.110 Let's give it a name. 26 02:14.160 --> 02:18.520 It's going to be local time datt off. 27 02:18.670 --> 02:29.240 We're going to get the value of 7 of 120 that we need on other instance it's going to be local 9 1 and 28 02:29.460 --> 02:34.500 this is going to be eight are sent 20 minutes the minute of the day. 29 02:34.700 --> 02:37.960 Instance even the diamonds joins us until Monday. 30 02:38.340 --> 02:46.150 I'm going to give local time d'arte until and then by the end of the time instance. 31 02:46.150 --> 02:49.800 Now we could get a --. 32 02:49.880 --> 02:51.720 It gives you a competition issue here. 33 02:51.740 --> 02:57.820 Why do you have to specify Zari have to specify what is a unit that you were expecting as output. 34 02:57.920 --> 03:06.760 So I'm going to need what is a number of minutes time difference between those so this one is give me 35 03:06.960 --> 03:13.360 the longest research but in the Keys of beat we go to Piedras or work here it gives you the minute little 36 03:13.360 --> 03:15.020 bit of the rate. 37 03:15.130 --> 03:19.490 So we don't give it a name as deaths. 38 03:19.560 --> 03:27.870 We go to the limited the runs along which is the difference between the two kinds Let's go and check 39 03:27.870 --> 03:28.620 the research. 40 03:36.380 --> 03:38.820 And the end time is always explosive. 41 03:38.840 --> 03:44.150 It's check the results so that it will be clear if you take a look at the time the difference the difference 42 03:44.350 --> 03:49.180 this 60 Minutes data difference between these two times. 43 03:49.220 --> 03:56.060 Let's go ahead and explore the curation class and use the a third that is part of the duration Clauson 44 03:56.100 --> 03:57.360 buys these shootings. 45 03:57.590 --> 04:01.580 Not a dime any longer dime one. 46 04:01.750 --> 04:11.960 This is going to return the ration Azer or no what we will do is we will explore what other does that 47 04:11.960 --> 04:22.070 are part of the duration object so duration darte particular it just supports two minutes to ours and 48 04:22.080 --> 04:23.010 get seconds. 49 04:23.220 --> 04:23.830 It's too late. 50 04:23.850 --> 04:25.050 Get seconds. 51 04:25.380 --> 04:31.680 Now I know and get units are going do like two minutes who are still nine. 52 04:31.980 --> 04:38.280 One thing if you notice here there is Norbit retired methods are supported us for the duration. 53 04:38.280 --> 04:44.470 That's a reason why duration is compatible only with local time and look lead and time. 54 04:44.490 --> 04:51.090 And what about almoner to just going to gumi the total number of minutes difference between these two 55 04:51.090 --> 04:51.800 things. 56 04:54.040 --> 05:03.960 Anderson check those and reserved the cool luminance gave you the resurged us Eckstine nets that explore 57 05:03.980 --> 05:06.350 some of the factors that are part of the division. 58 05:06.430 --> 05:10.570 Do you want to read duration off for some parts. 59 05:10.690 --> 05:11.570 There you go. 60 05:11.710 --> 05:21.960 And then we will pause the RS us the Ares and this will give you the duration as the four that's under 61 05:21.970 --> 05:27.190 us and check the oil if you Rondo's example I'm going to do. 62 05:27.310 --> 05:33.250 We know that it is going to represent the duration of three pars that's due to minutes and then see 63 05:33.250 --> 05:35.210 what is Allport that it is going to print 64 05:39.120 --> 05:47.660 you go let's run this example on Jager's said we're on those Day-Glo were it converted into Rs 2 minutes 65 05:47.930 --> 05:54.240 and then given the who served us one maybe because each are represent 60 Minutes. 66 05:54.320 --> 05:58.700 Here we have the RS 360 equal and 180 minutes. 67 05:58.910 --> 06:05.150 We want to create a duration of three minutes in dual blowing off minutes. 68 06:05.210 --> 06:12.620 And one thing if in order zero gain it just has the days Malise minutes and most of seconds and seconds 69 06:12.920 --> 06:20.230 really doesn't support any of the deep methods like the month year. 70 06:20.420 --> 06:25.760 So if you have any use cases that are leading to the pain relief and logic where you want to find the 71 06:25.760 --> 06:30.980 difference between the two times then please go ahead and use two Rhaetian if you have any data related 72 06:30.980 --> 06:31.730 compartments. 73 06:31.760 --> 06:35.570 Then please go ahead and use the fuel your gas. 74 06:35.570 --> 06:42.830 Now what we will do is we'll try to positive deed to the duration dark between matter and then check. 75 06:42.830 --> 06:44.220 Is it compatible or not. 76 06:44.260 --> 06:49.540 So I'm going to create Bates local aid. 77 06:50.960 --> 06:59.110 Dead people do local DA not now and then other instances are going to be a local one. 78 07:00.250 --> 07:02.880 God bless these people. 79 07:02.880 --> 07:06.300 Can you think by this what would happen. 80 07:06.470 --> 07:13.750 What I intend there that that will lead one that this is going to give me did not give you any number 81 07:13.760 --> 07:14.470 even issues. 82 07:14.470 --> 07:18.450 Let's check whether is it going to throw an exception during that on time. 83 07:19.370 --> 07:20.420 Well under US 84 07:23.070 --> 07:26.870 give you go exception the runtime. 85 07:26.880 --> 07:29.710 So I'm supported the unit seconds. 86 07:29.730 --> 07:35.870 Basically you cannot perform any kind of really good function out of this as part of the duration process. 87 07:35.880 --> 07:40.930 Even though it did not give you any compilation issues this is going to give you the compilation. 88 07:41.060 --> 07:43.560 The one thing you actually saw that in your mind. 89 07:43.560 --> 07:50.320 Duration is only for that time really did want another piece of it this weekend to the end of the material. 90 07:50.480 --> 07:51.100 Thank you for watching.
